This challenge is limited mainly by the relatively low capacity of available power sources. Another major aspect is the development of electric motors with High Specific Power (HSP) and high Torque per unit Rotor Volume (TRV). This paper deals with the motor intended as one of the propulsion motors for a light two-seater aircraft. The motor has a maximum power of 90 kW for a rotational speed of 3500 rpm and weight 18 kg. The article presents an analysis of the most important issues at the motor design stage, the physical model and the results of laboratory tests. The main attention was paid to the development of a motor solution that meets the basic design requirements, including, above all, limiting the motor’s weight. For this purpose, the following are analyzed: the selection of the appropriate type of motor, the selection of slot-pole combinations, the type of permanent magnets, the type of sheets in the stator core and issues reducing rotor losses. The strength analysis of the main mechanical elements is also presented.","PeriodicalId":192269,"journal":{"name":"2023 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133562770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The occurrence of PD is both a source and indication of insulation degradation in electrical machines. With the widespread electrification of transportation and many reliability critical applications, PD phenomenon remains a big challenge as it deteriorates the insulation system and can lead to premature failure of an electrical machine. Online condition monitoring using embedded sensors to detect PD in the insulation system has been suggested in the literature but has been difficult to implement due to geometrical constraints and bandwidth limitation of existing sensors. The proposed MASA overcomes these challenges. The design is based on the modification of polar coordinates equation of Archimedes spiral and its operation demonstrates how the geometrical constraint which inhibits other sensors can be overcome by physically integrating it within the end-winding of a machine. With its ultra-wide bandwidth (0.3 – 2 GHz), it is capable of effectively capturing the expected spectrum of PD in inverter-fed electrical machines, which is verified experimentally. Another novelty of the proposed sensor is its inherent ability to discriminate between commutation disturbance and PD pulses without the need for an external high-pass filter, making the solution suitable for condition monitoring and PD detection in inverter-fed electrical machine in service.","PeriodicalId":192269,"journal":{"name":"2023 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125918514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the impact on a system level for automotive application, an 800 V E-Drive is evaluated in a test rig. A 385 kW electric motor is used together with an 800 V Silicone-Carbide inverter. Two different tests are conducted, the first bring high accuracy efficiency measurements of the motor and inverter at a number of fixed operation points. The second test is the WLTC cycle in which the total E-Drive efficiency and on a component-level is measured over the total drive cycle. The results are presented and discussed where significant voltage dependency can be noted for the efficiency, both for the motor and inverter. Hence this paper highlights one of the challenges as automotive OEMs move towards higher voltages. Future studies to be conducted are mentioned in the discussion to further investigate how the inverter conditions will influence the total system efficiency and to show possible solutions to reduce the impact of the system voltage level.","PeriodicalId":192269,"journal":{"name":"2023 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129477674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
